x402-gated NFT data endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at `/api/v1/nfts/75` is part of the lowpaymentfee.com platform, which offers a collection of pay-per-request APIs gated via the x402 protocol on the Base network. The specific endpoint appears to serve NFT-related data (resource ID 75), though the exact response payload is not documented. Payment is settled in USDC (contract `0x8335…2913` on Base) at $0.02 per call (20,000 base units with 6 decimals). No API keys, rate limits, or subscriptions are required — callers simply attach an `X-PAYMENT` header with a valid x402 payment proof.
The broader lowpaymentfee.com platform advertises endpoints across several categories: data & analytics (metrics, reports, exports, insights), AI & ML (sentiment analysis, text summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are uniformly priced at $0.02 per request. However, this specific listing covers only the `/api/v1/nfts/75` endpoint, which is not listed on the platform's public landing page and has no dedicated documentation describing its request format or response schema.
The endpoint is live and returns a proper x402 challenge (HTTP 402) when called without payment. The method is POST and the output MIME type is `application/json`. Because there is no OpenAPI spec, no example responses, and no documentation for this particular NFT endpoint, the exact data returned is unknown.

Quality
The endpoint is live and returns a valid x402 challenge, but there is zero documentation for this specific NFT endpoint — no request schema, no response examples, and it is not even listed on the provider's landing page. The purpose and data returned are entirely unknown beyond the generic 'Premium API Access' label.
